i think it's important to add that in the nouns section under "neuter" not all neuter nouns end in -a in definite plural like åra. In fact, åra seems to be the exception rather than the rule. In my mind, most definite plural neuter nouns end in -ene, for example et menneske - menneskene (the humans/people), et teppe - teppene (the carpets), et bord - bordene (the tables) etc.

Yeah you're totally right on that it's dialectical. I'm glad you put up both variants though, any misconceptions was what I was trying to avoid :)
I don't know if it's of interest in regards to the article but in the Bergen-dialect they don't have "female" nouns. They'd actually say "jenten min" I guess.
